Title: Multiplexing system
IPC: H04J3/16
Filed: 1965-05-13
Abstract: 1,111,181. Data transmission systems. ULTRONIC SYSTEMS CORPORATION. 13 May, 1965 [29 June, 1964], No. 20312/65. Heading H4P. In a time division multiplex system data from a plurality of low speed sources is multiplexed with data from a high speed source. Each frame comprises data from the high speed source, data from half the low speed sources, synchronizing data, and a word indicating from which of the two groups of low speed sources the data comes. Timing pulses at both the receiver and transmitter are derived by divider-counters from clock pulses at the transmitted bit rate. At the transmitter, the high speed data source provides a word accompanied by sync. bits. These are removed and the remaining data passed to shift registers. The last of these is read out during part of each frame, the data being divided into 5-bit words to each of which is added a parity bit. Start-stop words from the low speed sources pass to a distributing arrangement comprising a number of shift registers. After removal of the start-stop bits, the 5-bit words from half the sources are multiplexed word by word and added to the frame, which is completed by the sync. and identity words. The next frame comprises data from the other low speed sources. At the receiver the frame is demultiplexed, the recovered high speed data having sync. bits added, similar to those removed at the transmitter. By inspection of the identity word the low speed distributer passes the low speed data to the correct group of outputs. If a parity error is detected an error signal is printed.

Filed: 1930-07-04
Abstract: 356,855. Casting stereotype. FISHBURN, J. E., The Island, Uxbridge, Middlesex. July 4, 1930, No. 20356. [Class 100 (ii).] A gauge for use in the casting of stereotype plates is of grid formation with the walls of each cell corresponding to the configuration of the sides of a plate whereby a series of plates may be produced which are connected together by relatively small metal ties. The gauge consist of a rectangular framework comprising longitudinal members 1, 2, Fig. 1, and curved side members 3. A longitudinal bar 6 extends between the members 3 midway between the members 1, 2 and is connected to the latter by transverse bars 7 which divide the frame into equal rectangular cells which are bevelled at 8 and have rounded corners 9. The inner surface of the bar 6 is provided with a series of depressions 10 ; similar depressions 11 are provided in the bar 1 and are arranged to open into space formed between the adjacent ends 12 of the side members 3. A metal strip 13 is inserted into the bar 2 and is provided with a series of ribs 14 extending upwardly of the gauge. To employ the gauge a flong mould 15, Fig. 5, bearing a series of juxtaposed impressions for a corresponding series of plates is arranged within a casting box 16, and the gauge is then placed in position over the mould so that ribs 5 provided at the ends of the gauge extend over the edges of the box 16. A curved plate 17 provided with side ribs is then placed in position on the gauge with its ribs extending into rebates 4 on the gauge. The plate 17 has circumferential grooves 18 in which the ribs 14 of the gauge extend to locate the grooves 18 relatively to the cells of the gauge. The members are then held in position in any manner and molten metal is poured into the space A formed between the extensions 12 of the side members 3 of the gauge. The molten metal flows through the depressions 11 formed in the bar 1, through the cells of the gauge arranged in communication therewith, then through the depressions 10 into the next series of cells. The plates thus cast are connected together by relatively small ties corresponding to the depressions 10 and the space between the plates 17 and the transverse bars 7. The grooves 18 in the plate 17 produce a series of corresponding ribs which form a bearing surface on the bottom of the stereotype plate. The gauge, which should possess a relatively small coefficient of expansion, may be made of a steel known under the registered Trade Mark " Invar."
